 Description
The hydraulic distributor Р120 is used for switching on/off and controlling of the working fluid between head flow generators (hydraulic pumps), head flow consumers (hydraulic cylinders, motors, etc.), and the tanks of hydraulic systems of mobile machines (electrical and diesel forklifts, excavators, auto-cranes, etc.).
Specifications Technical parameters: | Actuating force | -40C...+60C | | Hydraulic liquid -mineral oil based/hydraulic oil | | | Viscosity | 12 ...800 mm2/s | | Fluid temperature | -15C...+80C | | Filtration | 10 to NAS 1638 | | Max operating pressure, P=250; T=50 bar | A , B = 300 bar | | Leakage(A,B-T) | 30cm3/min at 120bar | | Nominal flow | 120 l/min | | Spool stroke | 10 mm,L12+/-10/6 | | Actuating force | < 300 N | Construction
The hydraulic distributor Р120 is a monoblock type with manual control. The body is made of cast iron 30, and the spools are made of carburized steel with hard chrome plating Mounting
The distributor is fixed with 3 bolts M10
Directional control valves are one of the most fundamental parts in hydraulic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a piston inside a cylinder which is electrically controlled. The movement of the cylinder restricts or permits the flow, thus it controls the fluid flow.
Directional control valves are mainly two types:
* Hydraulic and
* Pneumatic.
Hydraulic directional control valves are for a liquid working fluid (e.g. water, hydraulic oil) and pneumatic directional control valves are for a gaseous (usually air) working fluid.
